As the Supreme Court prepares to hear oral arguments in McCutcheon v. FEC, U.S. PIRG and seven other pro-democracy groups are speaking out on the urgent need for amending the Constitution to protect the integrity of our democracy.

Advocates are celebrating a significant milestone in the campaign for a constitutional amendment to overturn the U.S. Supreme Court’s 2010 ruling in Citizens United that opened the floodgates of money from corporations and the ultra wealthy into our political system. Support for the campaign now stands at one-third of what is needed for victory.

It has been barely a month since the Supreme Court issued its controversial Voting Rights Act (VRA) ruling — yet already, in states across the country, laws are being implemented and proposed that are designed to severely limit voting access, and that will ultimately harm American democracy.

Yesterday, in Shelby County v Holder, the Supreme Court struck down Section 4 of the Voting Rights Act. Section 4 was a critical piece of legislation that helped ensure the ability of eligible voters to cast a ballot regardless of race, age or gender, and the Court’s decision is a blow to voters’ rights.

To date, 15 states and nearly 500 municipalities have called upon Congress to overturn Citizens United and related cases by amending the Constitution. The introduction of these two joint resolutions today takes that call seriously and moves us two steps closer to ensuring that in our democracy the size of your wallet does not determine the volume of your voice.
